Re: Engineering Services

4.000 kW System
To Whom It May Concern:
We have received information regarding solar panel installation on the roof of the above referenced
structure. Our evaluation of the structure is to verify the existing capacity of the roof system and its ability
to support the additional loads imposed by the proposed solar system.
A. Site Assessment Information
1. Site visit documentation identifying attic information including size and spacing of framing
for the existing roof structure.
2. Design drawings of the proposed system including a site plan, roof plan and connection
details for the solar panels. This information will be utilized for approval and construction
of the proposed system.
B. Description of Structure:
Roof Framing: Assumed prefabricated wood trusses at 24” on center. All truss members
are constructed of 2x4 dimensional lumber.
Roof Material: Tile Shingles
Roof Slope: 22 degrees
Attic Access: Inaccessible
Foundation: Permanent
C. Loading Criteria Used
• Dead Load
o Existing Roofing and framing = 7 psf
o New Solar Panels and Racking = 3 psf
o TOTAL = 10 PSF
• Dead Load
o Existing Roofing and framing = 7 psf
o New Solar Panels and Racking = 3 psf
o TOTAL = 10 psf
• Live Load = 20 psf (reducible) – 0 psf at locations of solar panels
• Ground Snow Load = 0 psf
• Wind Load based on ASCE 7-16
o Ultimate Wind Speed = 95 mph (based on Risk Category II)
o Exposure Category C
Analysis performed of the existing roof structure utilizing the above loading criteria is in accordance
with the 2019 California Building Code, including provisions allowing existing structures to not
require strengthening if the new loads do not exceed existing design loads by 105% for gravity
elements and 110% for seismic elements. This analysis indicates that the existing framing will
support the additional panel loading without damage, if installed correctly.
2037 W Chandler
Ave11/23/22
Page 2 of 2
D. Solar Panel Anchorage
1. The solar panels shall be mounted in accordance with the most recent EcoFasten installation
manual. If during solar panel installation, the roof framing members appear unstable or deflect non-
uniformly, our office should be notified before proceeding with the installation.
2. The maximum allowable withdrawal force for a 5/16” lag screw is 235 lbs per inch of penetration as
identified in the National Design Standards (NDS) of timber construction specifications. Based on
two screws with a minimum penetration depth of 2½”, the allowable capacity per connection is
greater than the design withdrawal force (demand). Considering the variable factors for the existing
roof framing and installation tolerances, the connection using one 5/16” diameter lag screw with a
minimum of 2½” embedment will be adequate and will include a sufficient factor of safety.
3. Considering the wind speed, roof slopes, size and spacing of framing members, and condition of
the roof, the panel supports shall be placed no greater than 48” on centers.
4. Panel supports connections shall be staggered to distribute load to adjacent framing members.
Based on the above evaluation, this office certifies that with the racking and mounting specified, the existing
roof system will adequately support the additional loading imposed by the solar system. This evaluation is in
conformance with the 2019 California Building Code, current industry standards, and is based on information
supplied to us at the time of this report.
Should you have any questions regarding the above or if you require further information do not hesitate to
contact me.
Very truly yours,
